Abstract

PROBLEM TO BE SOLVED: To easily and quickly express movement of a large number of spectators serving as a background of a game. SOLUTION: A spectator polygon control part 220 determines the progress of a game. For example, in a soccer game, the game progress condition such as whether a player character shoots a ball to a goal or not and whether a player character on one side regains the ball from the other team or not is determined. On the basis of the determination result, the length yh of the opposite two sides of the spectator polygon is decided. A spectator drawing part 240 sets a mapping area matching the spectator polygon height Yh from a texture copying the spectators so as to draw the spectator polygon.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game apparatus for generating an image based on a given viewpoint in an object space, and executing the given game by displaying the generated image.

[0002]

2. Description of the Related Art In a game played by manipulating various characters that move in an object space, the environment surrounding those characters is expressed in detail in a detailed manner. The effect of improving the immersion feeling for the game is expected. For example, in a soccer game, drawing a spectator in the background and outputting cheering and cheering of the spectator according to the behavior of the player character, that is, deciding a shot or executing a pass, the actual soccer. It is possible to remind the stadium and amplify the player's emotions such as joy and impatience for the development of the game.

[0003]

However, there are few conventional sports games that express the dynamics of the audience in accordance with the development of the game. This is because the positions of the viewpoints in the object space are often limited, and the audience seats are far from those viewpoints.
This is because it was not necessary for the spectator to perform detailed movements without seeing the details, and it was difficult to express the movements of a large number of spectators closely.

However, in recent game machines, various processing capabilities and speeds such as a response process to a player's operation and an image generation process have been improved, and various game programs have been developed. It is now possible to freely change the viewpoint position in the game. Therefore, unlike the case where an image is generated from a limited viewpoint position, an image can be generated from a viewpoint closer to the audience seat, and lacks a sense of realism when the audience does not move up against the voice. Not only did it look rather unnatural.

[0005] In order to solve this problem, there is a method in which a plurality of textures depicting the audience are prepared and sequentially mapped to polygons installed in the audience seats, thereby expressing the appearance as if the audience is actually moving. Conceivable. However, a huge number of textures are required to smoothly and colorfully express the movement of the audience, and storing those textures not only wastes memory capacity, but may lead to game delay, The processing for the audience, which is the background of the game, was not realistic.

Alternatively, one texture drawn by the audience is mapped to a polygon having a fixed shape, and a plurality of textures are arranged in front, rear, left and right so that the surface is in front of the playground. Then, a method is also conceivable in which each polygon is vibrated up and down to express a state in which a plurality of spectators are moving. However, when the overlapping area of the polygons placed before and after is set to be small, or when the amplitude of the vibration is set to be large to express the excited state of the audience, etc. The lower end of the camera may be exposed and the audience may look unnatural.

An object of the present invention has been made in view of the above problems, and is characterized in that the movement of a large number of aggregates serving as a background in a game is more simply and realistically expressed.

[0008]

According to a first aspect of the present invention, an image of an object space including a character is generated based on a given viewpoint, and the generated image is displayed. A game device that executes a given game, and displays in and out of each of the plurality of aggregate objects arranged in the object space from the arrangement position, thereby displaying the aggregate objects. The display part is changed to express the dynamics of the aggregate (for example, the audience polygon control unit 2 shown in FIG. 12).
20).

According to a fourteenth aspect of the present invention, there is provided information for executing a given game by generating an image of an object space in which a character exists based on a given viewpoint and displaying the generated image. An information storage medium storing a plurality of aggregated objects arranged in the object space, by performing ingress and egress display from the arrangement position to change a display portion of the aggregated object. Information for expressing the dynamics of the aggregate (for example, the polygon control program 42 shown in FIG. 12).
0).

Here, the in-and-out display includes not only the in-and-out display that is actually hidden but also the display that makes it appear as though it is in and out. In addition, the aggregate object may be obtained by mapping a texture imitating the aggregate to a planar object. In this case, the texture to be mapped may be a still image or a moving image. The aggregate includes grass growing on a bank and the like, and spectators watching sports, horse racing, and other battles, games, and competitions.

According to the invention described in claim 1 or 14, for example, when the given game is a sports game and the aggregate is an audience, the image of the audience drawn on the aggregate object is one type. Even so, it is possible to express as if the audience is moving by displaying them as if they were moved in and out. Therefore, it is not necessary to store much image data, and moreover, it is possible to more realistically and easily represent a state where a large number of spectators are enthusiastic about the sport. In addition, since the entry / exit display is performed from the arrangement position, the lower end of the rear spectator does not appear at a position higher than the spectator existing in front, so that a problem such as an unnatural cut appears.

According to a second aspect of the present invention, in the game device according to the first aspect, the aggregate object includes, in a texture simulating the aggregate, a change in a display portion of the aggregate object. The corresponding portion may be mapped.

According to a fifteenth aspect of the present invention, in the information storage medium according to the fourteenth aspect, the display object of the aggregate object is included in the texture simulating the aggregate with respect to the aggregate object. Information for mapping a portion corresponding to the change may be included.

According to the second or fifteenth aspect of the present invention, for example, the aggregate object is rectangular, and the length in one direction is changed according to the progress of the game, and is mapped according to the length. By determining the texture area, it is possible to realize in-out display without expanding and contracting the image of the aggregate.

According to a third aspect of the present invention, in the game device according to the first or second aspect, the brightness and / or the color tone of the plurality of aggregated objects are arranged at the positions where the aggregated objects are arranged. It may be different depending on it.

Further, the change of the brightness and / or the color tone of the aggregated object may be changed in addition to the change depending on the arrangement position.
It may be in accordance with the time zone set in the object space, the season, the weather, the time zone in which the player executes the game, and the like.

According to the third aspect of the present invention, for example, when the audience is represented by an aggregate object, if the brightness and the color tone are changed between the front and the rear of the audience seat, the audience can be represented. Can be expressed not only by its size, but also by its brightness and shade. Further, for example, in a dome-shaped stadium, when expressing the audience seats including the first floor seats and the second floor seats, the second floor seats can be distinguished by expressing the second floor seats dimly. Express the existing feeling of overpressure and appeal to the player's sense of the size of the venue.

Further, as in the invention according to claim 4, in the game device according to any one of claims 1 to 3, the aggregate object may be constituted by one polygon.

In the information storage medium according to the present invention, information for forming the aggregate object by one polygon may be stored.

According to the invention described in claim 4 or 16, since the aggregate object is composed of a single simple polygon, processing such as in-out display and texture mapping can be performed easily and quickly. Can be performed.

According to a fifth aspect of the present invention, in the game device according to any one of the first to fourth aspects, a gazing point is set in the object space and the set gazing point is set to the set gazing point. It may be rotated facing the front.

According to a seventeenth aspect of the present invention, in the information storage medium according to any one of the fourteenth to sixteenth aspects, a gazing point is set in the object space, and the aggregate object is set at the set gazing point. It may include information for rotating the front of the camera.

According to the fifth or 17th aspect of the present invention, the front of the aggregate object faces the direction of the gazing point. Therefore, for example, when the audience is represented by the aggregate object, it is possible to represent a situation where the audience is always looking at the direction in which the point of regard is set.

According to a sixth aspect of the present invention, in the game apparatus according to the fifth aspect, the setting of the point of regard is
It may be changed according to the progress of the given game.

According to the sixth aspect of the present invention, the setting of the gazing point can be changed according to the progress of the game.
Therefore, in a game in which one character moves in the object space, for example, even if the position where the character exists is changed, by setting the gazing point with the change in the position, the aggregate ( For example, the audience can be set to always face the direction of the character.

According to a seventh aspect of the present invention, in the game apparatus according to the sixth aspect, the aggregate object is arranged in the object space even when the position of the gazing point is changed. The rotation may not be more than a given upper limit angle from the given direction.

According to this invention, for example, in a game in which the viewpoint moves in the object space, the upper limit of the rotation of the aggregate object in consideration of the arrangement position of the aggregate object and the moving range of the viewpoint. Is set, the rotation of the aggregate object can be restricted irrespective of the position of the gazing point. Therefore, since the position of the gazing point and the viewpoint is separated, the aggregate object rotates substantially parallel to the line of sight of the viewpoint, and the aggregate is unnaturally thin,
Alternatively, it can be prevented from appearing distorted.

In the game apparatus according to the sixth or seventh aspect, a given object existing in the object space or the viewpoint may be set as the point of interest. Good.

According to the eighth aspect of the invention, an object or a viewpoint can be set as a point of interest. For this reason, in a soccer game, for example, if the ball is set as the gazing point, it is possible to express a state in which the audience is eagerly observing the movement of the ball with the aggregate object always facing the ball. Also, if the viewpoint is set as the gazing point, it is possible to always direct the front of the aggregate object to the viewpoint, and the aggregate object rotates substantially parallel to the line of sight of the viewpoint, and the aggregate becomes Generation of an unnaturally thin or distorted image can be prevented.

According to a ninth aspect of the present invention, in the game device according to any one of the first to eighth aspects, the in-and-out display of the plurality of aggregate objects arranged is performed in accordance with the behavior of the character. It may be done.

[0031] In the information storage medium according to any one of the fourteenth to seventeenth aspects, a plurality of the aggregate objects arranged and arranged in accordance with the behavior of the character may be displayed. It may include information for performing.

Here, the behavior of the character is, for example,
In a game in which a plurality of characters compete for points or points, this includes the case where the characters perform an action that leads to a win or loss, such as acquiring points, deciding a technique, or launching an attack.

According to the ninth or eighteenth aspect of the invention, the movement of the collective can be expressed in accordance with the behavior of the character to be viewed from the collective. For example, in a soccer game, when a player character supported by a spectator (aggregate) has scored a goal, the entry / exit display of the aggregate object is periodically vibrated so as to represent an exciting venue. Can be. Therefore, it is possible not only to express a soccer stadium with a sense of reality but also to inform the player indirectly of the development of the game.

According to a tenth aspect of the present invention, in the game apparatus according to any one of the first to ninth aspects, the entry / exit display of the plurality of aggregate objects arranged is set at the position where the aggregate objects are arranged. By controlling for each region based on it, it is also possible to express the dynamics of an aggregate that is united between each region and between regions.

According to a ninth aspect of the present invention, in the information storage medium according to any one of the fourteenth to eighteenth aspects, the entry / exit display of the plurality of aggregate objects arranged is determined by the arrangement position of the aggregate objects. By controlling for each area based on the information, information for expressing a dynamic of an aggregate having a unity between the areas may be included.

According to the tenth or nineteenth aspect of the present invention, the aggregate object is controlled for each area. Therefore, a numerical value calculated to make a plurality of aggregate objects existing in one area vigorously, Since the parameters can be applied to an aggregate object existing in another area, the processing speed can be further improved. In addition, since the collective objects existing in the area can be controlled collectively, for example, a wave by an audience frequently seen in watching a ball game game,
Aggregates form a certain mass (or unite)
Working expressions can be performed more easily.

In the game apparatus according to the tenth aspect of the present invention, in the game apparatus according to the tenth aspect, the given game is a game in which two or more characters compete and the spectators watching the battle are gathered together. The game may be represented by an object, and the area may be divided depending on whether or not the area is for a spectator who supports a character to be operated by a player.

Here, the number of persons operating the characters existing in the object space is not limited to one, and may be plural. That is, when a game is executed by a plurality of players, an area of a spectator to support may be determined according to a character operated by each player.

According to the eleventh aspect of the present invention, it is possible to control the in / out display of the aggregate depending on whether or not the spectator supports the character operated by the player. So, for example, in a tennis game,
The player can double the pleasure of acquiring points by witnessing the movement of the audience when the character operated by the player acquires points, and when the opponent acquires points, You will be able to enjoy even more regret when you see the dynamics of the audience who support you. In this way, by making the audience distinct and energetic, the game is made more realistic, and the player is more attached to the score than the type of game that simply earns the score, improving the immersion in the game We can expect to do.

According to a twelfth aspect of the present invention, in the game apparatus according to the eleventh aspect, the color of the plurality of aggregate objects is set so that the spectators who support the character side to be operated by the player It may be different depending on whether or not it is the area.

According to the twelfth aspect of the present invention, the clothes and the like of the spectator are expressed in different colors according to the area where the spectator is present, that is, whether or not the area supports the character to be operated. can do. Therefore,
It is possible to instantly identify in which region a spectator present is supporting which character side.

According to a thirteenth aspect of the present invention, in the game apparatus according to any one of the first to twelfth aspects,
By changing the texture to be mapped to the aggregate object, the number of aggregates forming the aggregate object may be changed in real time according to the progress of the given game.

According to a twentieth aspect of the present invention, in the information storage medium according to any one of the fourteenth to nineteenth aspects, the texture to be mapped to the aggregate object is changed to configure the aggregate object. It may include information for causing the number of aggregates to be changed in real time according to the progress of the given game.

According to the thirteenth or twentieth aspect, it is possible to change the number of aggregates during game play. Therefore, for example, in a soccer game, if the score difference between two opposing teams is greater than a given score, the number of spectators is reduced, and if the close battle is unfolded, the spectators are recruited. Expressions such as increasing the number can be made, and a more diverse atmosphere can be produced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. In the following, a method of applying the present invention to a spectator present at a stand seat of a soccer stadium will be described. That is, a method of making the crowd a spectator and moving the spectator according to the progress of the game (soccer match) will be described, but the present invention is not limited to this.

FIG. 1 is a diagram showing an example to which the present invention is applied. FIG. 1A shows a case where the display area of the audience 50 is small.
(B) shows a case where the display area of the audience 50 is large. The audience 50 depicted in (a) is the audience 50 in (b).
The audience 50 shown in (b) is conversely represented as being pushed into the arrangement line 52 in comparison with the audience 50 shown in (a).
Are expressed as if they were drawn from the arrangement line 52 in comparison with. As described above, the present invention expresses the movement of the spectator by displaying the spectacle as if the spectator were put in and out of the position where the spectator is arranged.

In the following, the spectator is represented by mapping a texture imitating the spectator (hereinafter referred to as spectator texture) to one rectangular polygon (hereinafter referred to as spectator polygon). In addition, the movement of the spectator, that is, the ingress / egress display of the spectator, changes the area by changing the length of two sides of the rectangular spectator polygon, and maps the texture (in accordance with the change in the area) to the area ( This is performed by determining a mapping area.

FIG. 2 is a diagram for explaining the outline of the present invention. (A) is a figure showing an example of spectator polygon 60. The length (height h _y ) of the spectator polygon 60 in one direction of the rectangle is changed as time passes. The length (width w) of the audience polygon 60 in the other direction is constant.
(B) is a figure showing an example of spectator texture 64 imitating the whole body of the spectator. The spectator texture 64 does not have its entire area mapped to the spectator polygon 60,
Only the area corresponding to the area of the spectator polygon 60 at that time is mapped. That is, according to FIG.
The width of the spectator texture 64 corresponds to the width w of the spectator polygon 60, and the area corresponding to the height _hy of the spectator polygon 60 from the upper end of the spectator texture 64 is the mapping area 6.
Adopted as 6.

As described above, the length of one direction of the spectator polygon is changed with time, and the mapping area in the spectator texture is determined according to the length of the side of the spectator polygon. Without shrinking, it can be expressed as if it were taken in and out of the arrangement position. Hereinafter, a method for realizing the present invention will be described in detail.

First, a method for changing the height of the spectator polygon over time will be described. Note that benches and chairs are arranged in a staircase at stand seats (audience seats) in a general soccer stadium, and many spectators are designed to sit on each stage. Therefore, also in this embodiment, a method of expressing a situation in which a large number of spectators are present in the stand seats at each stage and enthralling in a soccer game will be described. First, for simplicity, one spectator polygon is vibrated. After describing the method of causing the control, a method of arranging and controlling a plurality of spectator polygons on the stand seat will be described.

FIG. 3 shows an audience polygon in the object space.
It is a figure showing an example in which 60 was arranged. In addition, shown in the figure
(X, Y, Z) means coordinate axes in object space
And the Y-axis direction indicates up and down in the object space.
It is. Further, as shown in FIG.
From the lower left are 1 (x₁, Y₁, Z
₁), 2 (x_Two, Y₁, Z_Two), 3 (x_Two, Y₁+ Y_h,
z_Two), 4 (x₁, Y₁+ Y_h, Z₁), Defined by
And y_hIs variable and the other values are constant.
You. That is, the audience polygon 60 is positioned with respect to the XZ plane.
The coordinates of the lower side are fixed and the upper side is fixed.
Only the Y coordinate changes. Therefore, the audience polygon 60
Expands and contracts only in the Y-axis direction while being fixed at the placement position
Will be done. Hereinafter, the Y-axis direction of the audience polygon 60
The side in the direction is called the vertical side, and the side in the direction horizontal to the XZ plane is the side
It is called a side.

The value of y _h can be changed by any method, but it is preferable that the value be changed continuously and periodically. For _{example, y h = A × cos {} 2π (t / T)} + L ... such (1), employing a function for periodically changing the value according to the time t. Here, A indicates the maximum amplitude at which the spectator polygon 60 vibrates, T indicates the period of the vibration, and L indicates the center value of the vibration. Figure 4 is a diagram showing an equation (1) as a function of time, the horizontal axis time t, and the vertical axis represents the value at time t of the function y _h. As shown in the figure, for periodically varying the value of y _h with a change in time, so that the spectator polygon 50 also expands and contracts over time.

As described above, the position of the lower side of the spectator polygon is determined in the object space, and the height is determined by a function of time as shown in Equation (1), so that the spectator polygon can be expanded and contracted up and down. It becomes possible.

Next, a state in which a large number of spectators are moving by arranging a plurality of spectator polygons in the object space, that is, at the stand seats in the soccer stadium, and expanding and contracting the vertical sides of the plurality of spectator polygons. The method of expression will be described.

FIG. 5 is a plan view showing an example of the soccer stadium 70. In the figure, a soccer stadium 70 has a ground 7 for executing a soccer game.
2 and a stand seat 74 surrounding the ground 72. Further, the stand seat 74 may be composed of first-floor stand seats 74-1 and 74-2 and a second-floor stand seat 74-3 as shown in FIG.

FIG. 6 is a plan view showing an enlarged example of a portion 76 of the stand seat 74 shown in FIG. 5, and is for explaining the arrangement of a plurality of spectator polygons. As shown in FIG. 6, each audience polygon 80-1, 80-2,.
−m (hereinafter simply referred to as spectator polygons 80) are arranged so as to face the ground 72. Specifically, the spectator polygon 80 is set so that the normal vector 84 of the spectator polygon 80 faces the center point 78 of the ground 72 (see FIG. 5). However, the root of the normal vector 84 is set on the midpoint of the horizontal side of the audience polygon 80, and is set so as to be always parallel to the XZ plane. That is, the spectator polygon 80 is perpendicular to the XZ plane, and is arranged such that one surface (a surface to be a table) is in front of the center point 78.

The audience polygons 80 arranged in a line
Is m, and the number of rows in the entire stand seat 74 is n.
And Further, the length of the side of the spectator polygon is set to such a length that a plurality of spectators are drawn, that is, the length of a spectator corresponding to the number of people who can sit on one bench in the stand seat 74. In the following, for the sake of simplicity, the description will be made assuming that the lengths of the sides of the spectator polygons existing in the stadium are all equal, but they may be different depending on the positions where the spectator polygons exist.

FIG. 7 is a perspective view showing an example in which spectator polygons 80 arranged in a line are looked up from the ground 72. As shown in the figure, the spectator polygons 80 are arranged in a line toward the ground. Also, the back, that is,
The spectator polygon 80 existing on the rear side is arranged at a position higher than the spectator polygon existing on the front side. The coordinate of each vertex of each spectator polygon 80 which is arranged on the stand seats 74, Y-axis direction length, that is, other than the value of the vertical side y _h,
All are fixedly set. Therefore, as soon as the value of y _h is determined, the position and shape of the spectator polygon 80 are determined.

As a method of independently changing the vertical sides y _h of the plurality of existing spectator polygons 80, a periodic function as shown in equation (1) is set for each spectator polygon. A method of vibrating at different maximum amplitudes and periods can be considered. However, here, to simplify the processing, the stand seat 74 is divided into several blocks. Then, each calculated value of the specific y _h to a plurality of spectators polygons 80 existing in one block, further, to the audience polygon 80 present the value of the calculated y _h in other blocks Even apply. That is, by turning using the calculated value of the y _h against spectators polygon 80 existing in one block in the plurality of blocks, to reduce the processing for varying the value of y _h audience polygon 80. Hereinafter, m audience polygons 80 radially arranged in a line in the stand seat 74 are defined as one block 82.

As a method of determining the vertical side y _h of the spectator polygon 80 existing in one block, a unique periodic function may be set for each spectator polygon 80 as described above. Here, equation (1) is modified as follows. y _hp = A * cos {2π} (t / T) + (p / m)} + L (2) Here, p means a variable taking an integer from 0 to m−1, and y _h the p subscripts, meaning that the value of the p-th y _h. That is, the value of y _h at time t is represented by m
Is calculated. Then, by assigning the calculated m values to the spectator polygon 80 in the block, it is possible to make it look as if each of them vibrates differently. Further, passing the value of the calculated the m y _h to another block,
The inherited value is assigned to each spectator polygon 80 for each block. The phase difference of m y _hp is the amount of one period and m equal parts.

Here, m calculated by changing the variable p
If the values of y _hp are assigned to the audience polygons 80 arranged in a line in the block in the order of calculation, that is, in the order of the value of p, the audience polygon 8
0 will fluctuate as if it waves in units of columns. In order to avoid this problem, the calculated m values are
Individually assigned to each spectator polygon 80. The value of s is
Set according to the value of m.

Since the amplitude of all spectator polygons is determined by one formula, the cycle and the maximum amplitude of all spectator polygons are equal, but generally the cycle and height of vibration of a person are large. There is no individual difference and it doesn't look so unnatural. Therefore, the length of the vertical side of the audience polygon 80 can be changed easily and without any discomfort according to the above equation (2).

However, when the above equation (2) is adopted, the spectators existing in the soccer stadium always vibrate in a constant manner even in an enthusiastic scene in a soccer game, and may look mechanical. . Therefore, several vibration modes are defined, and the maximum amplitude A, the cycle T, and the center value L of the vibration are set to be different for each mode. For example, a vibration mode such as a goal mode when the player character has scored a goal, an attack mode when the attack and defense are reversed, a wave mode that is executed at regular intervals, and a watching mode in a state other than the above modes are set. I do. In each of the vibration modes other than the watching mode, a time during which the mode is maintained is set, and the vibration mode is switched by counting the time from the mode start time.

FIG. 8 shows the equation (2) in each vibration mode.
FIG. 4 is a diagram showing an example of a parameter table 44 for storing values of a maximum amplitude A _k , a period T _k , and a center value L _k of vibration. Here, the subscript k indicates each vibration mode, 1 corresponds to the goal mode, 2 corresponds to the offensive mode, 3 corresponds to the wave mode, and 4 corresponds to the watching mode. Then, by setting each parameter to a value appropriate for each vibration mode, it is possible to produce various dynamism of the audience. For example, in the goal mode, the center value of the vibration L
_By setting ₁ and the maximum amplitude A ₁ to be large and the cycle T ₁ to be slightly small, it is possible to express a state that the audience stands up from the bench and is enthusiastic. Conversely, in the watching mode, by setting the center value L ₄ and the maximum amplitude A ₄ of the vibration to be small and the period T ₄ to be long, the state in which the audience is sitting on the bench and watching the game with a little excitement is expressed. In this way, a movement according to the progress of the game is realized.

Also, in the wave mode, as shown in the parameter table 44 of FIG.
Is taken to be an integer value of n−1, and y _h is calculated as a number equal to the number of blocks (n). And the calculated n
Allocating in order a value of number of y _h in each block. Furthermore, within each block, adopted for all audiences polygons 80, the value of the assigned y _h as the length of the vertical side. Therefore, in the wave mode, all the vertical sides of the spectator polygon 80 in the block have the same length. Therefore, by setting the maximum amplitude A ₃ , the cycle T ₃ , and the center value L _{3 of the} vibration to be large, it is possible to express a state in which a large wave slowly flows through the stand seat 74. Further, the timing of executing the wave may be a specific timing in a soccer game such as during a side change or at the time of a side kick, or may be performed periodically for a fixed time from the start of play.

As described above, by setting a plurality of modes, it is possible to express the enthusiasm of the spectator at the time of the goal, the wave executed by the spectator at a timing, and the like. Note that, depending on the type of soccer stadium, the spectators may sit separately for each team they support. In this case, according to the above-described method, the spectator is enthusiastically active even when the opponent team has made a goal. In order to avoid such inconsistencies, the stand seats were split into two groups,
The vibration mode is determined for each group to control the audience polygons present in each block. So, for example,
When the team A has a goal, the reaction of the spectators can be differentiated, for example, the team A cheering side is activated in the goal mode, and the team B cheering side is vibrated in the watching mode.

In the above description, the normal vector of the spectator polygon is directed to the center point of the soccer ground. However, the change in the position of the ball or the expected player character or the moment when the player character determines a shot is taken. The direction of the normal vector of the audience polygon may be changed according to the progress or progress of the game. In other words, the normal vector of the spectator polygon may be directed to an object to be a gaze target of the spectator according to the progress of the game.

Specifically, for example, as shown in FIG.
The soccer ground is divided into a plurality of areas, and in each area, the gazing points 90-1, 90-2,.
Is set). It is also possible to determine in which of the divided areas the ball exists, and to set the normal vector of the spectator polygon in the direction of the gazing point 90 set in the area where the ball exists. Good. In other words, the line segment connecting the point of gaze set in the area where the ball exists and the midpoint of the side of each spectator polygon always intersects perpendicularly with the side.

In this case, not only the Y coordinate of the upper side of the spectator polygon but also the X and Z coordinates change. The values of the X and Z coordinates of the spectator polygon are calculated using the fact that the direction of the normal vector of the spectator polygon is always parallel to the line connecting the midpoint of the horizontal side and the point of interest. FIG.
It is for explaining an example of a method of calculating the X and Z coordinates of the spectator polygon 92, and is a plan view of the spectator polygon 92 as viewed from above in the object space, that is, from the Y-axis direction. As shown in the drawing, when the angle between the normal vector 94 and the Z-axis direction is ∠θ, the length of the horizontal side is w, and the coordinates of the midpoint of the horizontal side are (x, y), the audience polygon X of each vertex of the 92, Z-coordinate _{(x 1, z 1),} (x 2, z 2) _{is, x 1 = x + (w} / 2) * sin (θ-π / 2), z 1 = z + ( w / 2) * cos (θ-π / 2), x ₂ = x + (w / 2) * sin (θ + π / 2), z ₂ = z + (w / 2) * cos (θ + π / 2) be able to.

However, in the case where the ball goes out of the field during a match or in a scene other than the match, the normal vector of the spectator polygon is directed to the center point of the soccer field so that the direction of the spectator is not biased. Further, it is not reasonable to execute the above calculation for all the spectator polygons existing in the object space. Therefore, only the normal vector of the spectator polygon existing in the front row of each block may be calculated and applied to all spectator polygons existing in the same block.

When the position of the gazing point is freely set in the soccer field, the spectator polygons are arranged obliquely with respect to the line of sight of the viewpoint, and the spectator may look unnaturally thin or distorted. In order to prevent such a problem, it is necessary to limit the rotation angle of the spectator polygon with respect to the Y axis. For example, as shown in FIG. 9, by setting the gazing point 90 in each area to be slightly above the center of the soccer ground, the gazing points 90 are arranged diagonally so that the audience polygons appear thin even at all viewpoint positions. Can be prevented.

Next, the spectator texture to be mapped to the spectator polygon 80 whose length of the vertical side is determined will be described. FIG. 11 is a diagram illustrating an example of the audience texture 86. A plurality of spectators are drawn on the spectator texture 86, and areas other than the spectators are set to be transparent. Therefore, a spectator behind can be seen from between spectators. The width U of the spectator texture 86 satisfies the relationship U = γ * W with respect to the width W of the spectator polygon, and the spectator texture 8
The vertical width V of 6 satisfies the relationship V = γ * (A + L). Here, γ is a proportionality constant for making the size of the spectator texture 86 correspond to the spectator polygon 80, and the size is always constant. That is, audience texture 8
6 is projected onto the spectator polygon 80, 1 / γ
Will be executed based on A and L are
Means the maximum amplitude A and the center value L of the vibration shown in equation (2),
Set the largest value among the values described in the parameter table.

[0073] mapping area for spectators polygon 80 spectators texture 86, from the upper end of the audience textures (and on the direction of the audience's head is drawn), in accordance with the length y _h of the longitudinal sides of the audience polygon 80 decide. In particular,
As shown in FIG. 11, the coordinates of the four vertices in the audience texture 86 are set to 1 (u ₀ , v ₀ ),
If 2 (u ₁ , v ₀ ), 3 (u ₁ , v ₁ ), and 4 (u ₀ , v ₁ ) are defined, the area mapped to the audience polygon 80 is 1 ′ (u ₀ , v ₁ − γ * y _h ), 2 ′ (u ₁ , v ₁ −γ
* Y _h ), 3 (u ₁ , v ₁ ), 4 (u ₀ , v ₁ ).

As described above, since the mapping area of the spectator texture 86 is determined from the direction in which the spectator's head is drawn in accordance with the expansion and contraction of the vertical side of the spectator polygon 80, the spectator image is not expanded or contracted. Expressed as moving up and down. Further, the proportionality constant for associating the spectator texture with the spectator polygon can be fixedly defined irrespective of the fluctuation of the spectator polygon.

An attribute for indicating the address of the audience texture is added to each audience polygon. The spectator polygons and spectator textures may correspond one-to-one, or one spectator texture may be applied to a plurality of spectator polygons. Further, an attribute for instructing luminance or light / dark may be added to the spectator polygon so that the luminance or light / dark of the spectator texture to be mapped differs depending on the position where the spectator polygon is arranged. For example, the second floor stand seat 74-3 of the soccer stadium shown in FIG.
Is set to darken the light and dark attributes of the spectator polygon existing in the first place and the light and dark attributes of the spectator polygon present in the first floor stand seats 74-1 and 74-2 are set. In this way, by giving lightness and darkness according to the position, depth and height can be expressed, and a more powerful and realistic image can be generated.

Next, a block configuration for realizing this embodiment will be described. FIG. 12 is a diagram illustrating an example of a functional block according to the present invention. In the figure, functional blocks include an operation unit 10, a processing unit 20, a display unit 30,
And an information storage medium 40.

The operation unit 10 is used by the player to input operation data. The operation data obtained by the operation unit 10 is output to the processing unit 20.

The processing section 20 controls the entire system, issues commands to each block in the system, game processing, image processing,
It performs various processes such as sound processing, and its function is performed by various processors (CPU, DSP, etc.) or ASIC.
(Eg, a gate array) or a given program. The processing unit 20 mainly includes:
A game calculation unit 22 and an image generation unit 24 are included.

The game calculation unit 22 performs a selection screen setting process, an object space, ie, a soccer stadium construction process, the position, orientation, speed, and the like of each character or ball.
Various game processes such as a process of obtaining a traveling direction and the like, a process of checking hits between a ball and a character, a process of calculating a viewpoint position and a line of sight, and a process of determining a game based on rules of a soccer game are performed by the operation unit 10. It is executed based on operation data, a game program 42 read from the information storage medium 40, and the like. When the coordinates of the viewpoint are determined, the coordinate information of the character or the like is transmitted to the image generation unit 24.
To generate an image based on the viewpoint. In addition, the game calculation unit 22 includes a spectator polygon control unit 220 for controlling spectator polygons arranged at a plurality of stand seats in the constructed soccer stadium.

The spectator polygon control unit 220 executes a process for controlling the vibration of a plurality of spectator objects arranged in the soccer stadium constructed by the game calculation unit 22 according to the polygon control program 420. In other words, the vibration mode is determined by determining the progress of the soccer game, such as whether the player character has scored a goal, whether one team has taken the ball from the other team, and entered the offense. For example, when one player character has scored a goal, the time from that moment is counted and the goal mode is set within a predetermined time.

[0081] Then, the audience polygon controller 220 substitutes the parameters corresponding to the vibration mode determined from the parameter table 44 to read Te formula (2), determining the value of the m or n number of y _h at that time . Furthermore, the audience polygon controller 220 determines the vertex coordinates of the spectator polygon accordance with the calculated y _h, and outputs the coordinate data to the image generating unit 24, an attribute, the value of the height y _h.

Further, the spectator polygon control unit 220 determines in which area of the soccer ground the ball is divided, based on the coordinate data of the ball determined by the game calculation unit 22. Then, the direction of the normal vector of the spectator polygon with respect to the fixation point set in the area where the ball exists is determined, and the X and Z coordinates of each vertex of each spectator polygon are determined.

The image generation section 24 executes processing for generating image data according to an instruction signal input from the game operation section 22, various kinds of coordinate information, and the like.
P, an IC dedicated to image generation, and hardware such as a memory. Then, the image generation unit 24 outputs the generated image data to the display unit 30 to display the image data. Also,
The image generation unit 24 includes an audience drawing unit 240 that executes a process for rendering the audience polygon input from the game calculation unit 22.

The spectator drawing unit 240 receives the spectator polygon coordinate data, attributes, and height h _y from the spectator polygon control unit 220.
When the value is entered, read the audience texture corresponding to the attribute from the information storage medium 40, on the basis of the mapping area setting program 422 to determine the mapping area corresponding to the height y _h entered. Then, a display image is generated by mapping the determined mapping area to a corresponding spectator polygon.

The display unit 30 outputs image data input from the image generation unit 24 to a display screen.
It can be realized by hardware such as T, LCD, and HMD.

The information storage medium 40 is realized by hardware such as a CD-ROM, game cassette, IC card, MO, FD, DVD, memory, and hard disk.
The game program 42, the parameter table 44, the audience texture 46 and the like are stored. The game program 42 includes programs (specifically, a polygon control program 420 and a mapping area setting program 422) for executing spectator control processing and polygon drawing processing to be described later.

Next, spectator control processing and polygon drawing processing 1 and 2 executed by the spectator polygon control section 220 and the spectator drawing section 240 will be described below with reference to the flowcharts shown in FIGS. These processes are executed for each frame.

FIG. 13 is a flowchart for explaining the audience control processing. In the following, K is a flag for identifying two teams that compete in a soccer game. For example, K = 0 is assigned to team A, K = 1 is assigned to team B, and so on. In the following,
The blocks of the total number n existing in the stand seat are sequentially processed from one end of the stand seat. The transition of the block to be processed is indicated by a variable i, and the first block number of the K (= 0) team is K0_s, and the last block number is K0_
e, similarly, the first block number of the K (= 1) team is K1_s, and the last block number is K1_e.

In the figure, first, the spectator polygon control unit 220 sets K to zero, and sets the variable sn to K0_s.
And K0_e is substituted for the variable se (step S1). Subsequently, the spectator polygon control unit 220 determines whether or not the K team is in the goal mode (step S2). If the mode is the goal mode, the parameters of the goal mode are read from the parameter table 44 (step S3), and the process proceeds to step S8. On the other hand, if it is determined in step S2 that the current mode is not the goal mode, it is determined whether the K team is in the offensive mode (step S4). In the case of the offensive mode, the parameters of the offensive mode are read from the parameter table 44 (step S5), and the process proceeds to step S8. If the mode is not the offensive mode in step S4, it is determined whether or not the mode is the wave mode (step S6).

If it is determined in step S6 that the mode is not the wave mode, the spectator polygon controller 220 reads the parameters of the watching mode from the parameter table 44 (step S7). Then, the read parameters are substituted into equation (2), and the m y
The value of _h is calculated (step S8).

[0091] Then, the audience polygon controller 220 assigns the value of y _h calculated for each block in each spectator polygon. First, the variable i is set to sn. That is, the first block in the K team is read (step S
9). Then, by executing polygon drawing processing 1 by the spectator polygon control unit 220 and the spectator drawing unit 240, the spectator polygon control unit 220 terminates the drawing process of the spectator polygon existing in the i-th block (step S10). , I (step S1)
1) It is determined whether or not i is se, that is, whether or not the processing has been completed for all blocks in the K team (step S12). If i = se is not satisfied, the process returns to step 10, and if i = se is satisfied,
Move to step S19.

On the other hand, if it is determined in step S6 that the mode is the wave mode, the spectator polygon control unit 220 reads the parameters of the wave mode from the parameter table 44 (step S13) and substitutes the parameters in equation (2). . Then, the value of y _{h at} the time is calculated as the total number n ′ of blocks in the K team (step S1).
4). Subsequently, i is set to sn (step S15). Then, the spectator polygon control unit 220 and the spectator drawing unit 24
By 0, polygon drawing processing 2 is executed (step S16).

At step S16, when the polygon drawing process 2 existing in the i-th block is completed, the spectator polygon control unit 220 adds 1 to i (step S17). And whether i is en, ie,
It is determined whether or not the processing has been performed on all blocks in the K team (step S18). If i = en is not satisfied, the process returns to step S16.

In step S18, if i = en is satisfied and processing for all blocks in the K team has been completed, the spectator polygon control unit 220 determines that K is 1
Is determined (step S19). If K = 1 is not satisfied, 1 is set to K, K1_s to sn, and en
Is substituted for K1_e (step S20), and step S2
And the process of the K (= 1) team is executed. On the other hand, when K = 1 is satisfied in step S19,
This processing is completed assuming that processing for all spectator polygons in the stand seat has been completed.

Next, polygon drawing processing 1 will be described. FIG. 14 is a flowchart for explaining polygon drawing processing 1. In the following, this process will be described using the variables j, k, and l. j is a variable taking an integer from 0 to m-1, and indicates the number of each spectator polygon. In the following, spectator polygons arranged in a line in a block are sequentially processed from one end. Therefore, for example, j = 0 indicates the spectator polygon at the head (front row) and j =
A number 1 is given to indicate a spectator polygon existing behind the number, and so on. K and l are variables used to allocate the m calculated y _h values to the m spectator polygons at s intervals.

In FIG. 14, the spectator polygon control unit 22
0 means that first, the arguments j, k, and l are replaced by j = 0, k = 0, l =
i is set (step S30). i is a variable indicating the number of a block in the spectator control processing, and is set as an initial value of l to apply y _h to the spectator polygon.
Is shifted for each block. Subsequently, k is replaced with 1 + s (step S31). And ｛mod (k /
m) The value of} th y _h adopted as the height of the j-th spectator polygons (step S32), and determines the vertex coordinates of the j-th audience polygon. Here, mod (k / m) means a remainder obtained by dividing k by m. Further, the audience polygon controller 220 outputs the determined audience polygon coordinate data, the value of the attribute and y _h audience drawing unit 240.

The spectator drawing unit 240 reads the spectator texture corresponding to the attribute input from the spectator polygon control unit 220 from the information storage medium 40, determines a mapping area based on y _h (Step S33), and determines the mapping area according to the attribute. The image is drawn with the added brightness and contrast (step S34).

In step S32, when the height of the j-th spectator polygon is determined, the spectator polygon controller 220
Replaces l with the value of k (step S35), and substitutes 1 for j.
Is added (step S36). Then, it is determined whether or not j is m−1, that is, whether or not the drawing processing has been performed on all the spectator polygons in the block (step S37). If j = m−1 is not satisfied, the process returns to step S31, and the j-th spectator polygon drawing process is executed. If j = m-1 is satisfied, the processing is terminated assuming that the processing of drawing all the spectator polygons existing in the i-th block has been executed.

Next, the polygon drawing processing 2 executed in the wave mode will be described with reference to the flowchart shown in FIG. In the figure, the spectator polygon control unit 220 detects the p = i-th numerical value (step S40). Here, p means an argument in the equation (2), and i is an argument meaning a block number in the audience control processing. Then, the height of all the spectators polygons present in the i-th block and the value of p = i-th y _h (step S41), for each spectator polygon audience drawing unit 240 coordinates data, attributes, the y _h Output the value.

On the other hand, the spectator drawing section 240 reads the spectator texture corresponding to the attribute of each spectator polygon input from the spectator polygon control section 220 from the information storage medium 40,
Determine the mapping area based on y _h (step S
42). Then, each spectator polygon is drawn based on the luminance / brightness / darkness attributes (step S43), and the process ends.

The game program, the program for executing the spectator control process and the polygon drawing processes 1 and 2, the parameter table 44, the spectator texture 46, and the like are stored in the memory 510 as an information storage medium on the system board 508.

The present invention is not limited to those described in the above embodiments, and various modifications can be made. For example, in the present embodiment, the spectator polygon has been described as pointing in the direction of the gazing point set in the area where the ball exists, but the direction of the spectator polygon may be changed with the ball itself as the gazing point. Good. Alternatively, a setting may be made such that the player character faces the player character having ownership of the ball or a viewpoint (virtual camera) that freely moves in the object space.

However, when the gazing point is set to the ball or the player character, the spectator polygons are arranged obliquely to the line of sight of the viewpoint, and the spectators may be displayed unnaturally thin or distorted. . In order to prevent such display, an upper limit is set for the rotation of the spectator polygon with respect to the Y axis, and even if a ball or character as a gazing point moves, if the rotation angle reaches the upper limit, it is set so as not to rotate. Specifically, for example, based on the case where the normal vector of the spectator polygon is directed to the center of the soccer field, an angle area that can be rotated left and right from that direction is set. And
If the angle between the normal vector of the spectator polygon and the reference direction with respect to the position of the gazing point exceeds the set rotatable angle area, the direction of the normal vector is set to the upper limit of the angle area.

Also, in the present embodiment, it has been described that one spectator texture corresponds to the spectator polygon. However, the spectator texture to be mapped to each spectator polygon is changed for each vibration mode, or for each fixed time. It may be changed to. For example, there are multiple audiences in prayer poses, multiple audiences with both hands open to express joy, multiple audiences holding hands together and raising their heads above, Prepare various audience textures, such as one depicting the audience watching a game. Then, when the vibration mode is determined in the audience control processing, a texture address corresponding to the vibration mode is given to the audience polygon in each block.

Specifically, an audience texture address table 700 as shown in FIG. 20 is prepared. The address table 700 stores each vibration mode and a plurality of spectator textures corresponding to the vibration mode. That is, the goal mode corresponds to a plurality of textures imitating a spectator in an exaggerated pose, and the wave mode corresponds to a plurality of textures in which an adjacent spectator holds hands and raises the head. . A plurality of spectator textures corresponding to each vibration mode may be variously changed and mapped to one spectator polygon. Alternatively, in one vibration mode, the number of spectator textures mapped to one spectator polygon may be limited to one.

Alternatively, a plurality of spectator textures in which a plurality of spectators are crowded and a plurality of spectator textures in which intermittent spectators are present are prepared. And two to play
If the score difference between the two teams is equal to or greater than a predetermined score, the attribute of a small number of spectators is given to the losing team's spectator polygon, and the attribute of a large number of spectators is given to the winning team's spectator polygon. By doing so, the audience texture corresponding to the attribute given to each audience polygon may be mapped.

As described above, during the play, by changing the contents of the spectator texture mapped to the spectator polygon in accordance with the progress of the game, that is, the winning or losing of the team in the soccer game or the behavior of the player character, the emotion of the spectator is changed. Can be expressed more realistically. In addition, since the attitude and dynamism of the spectator can be expressed in detail in accordance with the progress of the game, it is possible to give pressure to the game player or to inspire the game player.

The color of the audience's clothes may be changed for each team to support. For example, if team A has red uniform and team B has blue uniform,
The team A's cheering party's clothes are set to red, while the team B's cheering side are set to blue. In this case, a plurality of spectator textures with different colors of clothes may be prepared for each group supporting each team, but it is assumed that each spectator polygon has the color data of the clothes, and this drawing data is used for drawing. The configuration may be such that the color of the audience's clothes is determined based on the audience. In this way, by changing the color of the spectator's clothes for each cheering team, it is easy to determine which team the spectator is supporting and it is possible to indirectly inform players of the progress of the game Becomes

In the above embodiment, the audience polygons arranged in a row on the stand seats are described as being treated as one block. However, the way of taking the blocks is not limited to this. For example, spectator polygons may be sparsely arranged in a stand seat, and may be grouped into a predetermined number of blocks, or a plurality of spectator polygons 600 arranged toward a ground 608 as shown in FIG. One block 602 may be arranged so as to be alternately shifted so that the gap between adjacent blocks is the center of the blocks existing before and after the block. As described above, when the block unit is set to be small, the wave block 604 may be newly set, and the wave may be executed in units of the wave block 604.

Also, the number of spectator polygons present in each block has been described as being unified to m, but the number may be different for each block. Incidentally, when determining the length y _h of the longitudinal sides of the audience polygons exist in one block, for each spectator polygons have been respectively described as providing a unique value, the number of spectators polygons in block A smaller number of y _h may be calculated and reused in the block. Also, although the length y _h of each spectator polygon has been described as periodically changing using Equation (1) or (2), the length may be set using a non-periodic function.

In the above embodiment, a soccer game has been described as an example. However, the present invention is not limited to this. In addition to a ball game such as a basketball game, a baseball, a volleyball game, a judo or a sumo wrestling game, It can also be applied to audiences in martial arts games and audiences in concerts and performances. Or,
The present invention may be applied to vertical movement of a press machine in a factory, sunrise and sunset, shaking of grass, drawer of a desk, an enemy character in a shooting game, and the like.
For example, as shown in FIG. 22, a texture of a long grass such as a reed may be mapped to a polygon whose vertical side length changes with time, and a manner in which the grass sways may be expressed. In these cases, the direction in which the object (or polygon) is expanded or contracted is not limited to the vertical direction, but may be expanded or contracted in the horizontal direction.

[0122]

According to the present invention, the movement of the spectator is expressed by displaying the spectator in and out of the arrangement position. Therefore, unlike the case where a polygon having a fixed size is vibrated, there is no problem that the lower end of the rear polygon is exposed and the audience looks unnatural. In addition, as the display for taking in and out of the audience, the length of the rectangular polygon in the vertical direction is changed with time, and the texture area to be mapped is determined according to the length. For this reason, since the magnification at the time of mapping the texture to the polygon is constant regardless of the variation in the size of the polygon, the drawing process can be relatively easily performed, and the audience can be expressed without stretching or shrinking. .

Further, since a plurality of vibration modes are provided to determine which vibration mode corresponds to the present time, and the in / out display according to the determined vibration mode is executed, the audience according to the progress of the game can be displayed. Can express dynamism. Further, the expansion and contraction vibration of the rectangular audience polygon is controlled in block units. For this reason, if the vibration of the spectator polygon existing in one block is calculated, it can be applied to the spectator polygon existing in another block, and the processing can be further reduced. In addition, since the brightness, light and shade, color, and the like are changed for each block, it is possible to realize an expression that takes into account the location where the audience exists.

Further, it has been described that the direction of the normal vector of the spectator polygon is directed to the direction of the line-of-sight target object related to the development of the game. Therefore, it is possible to express the audience watching the game more realistically.
